|With a cold engine and battery pack, start the car, idle in neutral with the e-brake on. Go in the back of the car, and confirm that no fans are running. |
Put the modified paper clip into either of the two end pins. Both fan and blower should run at full speed. Test complete. Remove the jumper, and if you are a true environmentalist, re-bend it into the original paper clip shape, so you don't waste it.
Test complete, plug the fan connector back into the controller board, go to next step.
